IMPROVEMENT IN COMBINED G4RAIIVIZIIIRILL, SEED-SOWER, .AND CORN-PLANTER.

MWF-

The Schedule referred to in these Letters Patent and making paxt of the same.

To all whom 'it may conce/rn Be it known that I, DAVID EVANS, of Newton, in the county of Jasper, and State of Iowa, have invented a new and useful Combined Grain-Drill, Seed- Sower, and Oorn-Planterg and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this speciticatiomin which-- Figure 1 is a plan view.

Figure 2 is a transverse section.

Figure 3 is a side elevation.

Figure 4 is a plan view of the feed-bar.

Figure 5 is a section.

V Figure 6 is a plan of the screen used in sowing broadcast.

Figure 7 is aplan of the box to which the tubes are attached.

YFigure 8 is a section of the same.

The same letters in all the ligures relate to identical parts.

My improvements relate to the combination and arrangement of ,parts adapted to drilling, or sowing grain and planting corn, and their nature and character will be hereinafter set forth.

In the annexed drawings- A A are. the wheels, and

B, the axle. l v

O is the hopper, which is attached below the hounds, by a bolt, c,.on,which it may be made to oscillate by mea-ns of the lever C', so as to throw the operating-mechanism int-o or out-of gear.

. The hopper 'may be used in one continuons chamber, orit maybe subdivided into compartments, by the insertion of transverse-sliding partitions, when it is to be used in planting corn.

The grains pass through openings in the bottom of the hopper, into chambers formed in the sliding feed-har D, which is constructed intwo parts, as clearly shown iu figs. 4and 5, the lower part, D', being made so, that by sliding it, the apertures, or chambers may-be enlarged or diminished,according to the character of the work intended to be performed. It may be regulated 'by means of a rackand pinion, d, or by means of a set-screw, Las maybe preferred.

The screen E is' swung below the feed-bar, uponV hangers, which permit its oscillation.

Below the screen is a concave trough, F, which, catching the grain, delivers it through the tubes in fui-rows formed by the shoes T, attached by rods to the frame, and so set, by adjustable nuts, as. to vpermit vthem -to be regulated as to their depth, and to allow the removal of thosenot needed, when the machine is changed from a drill t-o a corn-planter.

The grain is covered by the grooved wheel K, running behind the tubes. This Wheel is used only for covering corn.

Thecams G and G', attached to the wheels, and revolving with them, are rods, or plates formed to act upon rods attached to the ends of the feed-bar D and screen E, and give them a longitudinally-reciprocating motion. l

. The cam G gives a rapid motion, for drilling; the cam G gives'a slower motion, for planting corn. v

iA lever may also be attached to the feed-bar, so that, disengaging the cams, the feed-bar may be moved by hand periodically, as required in planting corn.

A double revolving barrow, L, is attached, by rods, so that it may be removed, or attached so as to follow after the tubes and cover the grain. This barrow is suspended upon a lever, L, so that it may be raised or lowered as desired. One half may be folded up by raising it on hinges, by means ofthe cord L The bar L2 is hinged to the topof the barrow, upon its edges, having pins .projecting from its opposite edge, by means -of which the barrow may be prevented from revolving; or by swinging it by means of a lever, so as to raise the pins out of the reach of. the teeth, the harrow may be permitted to revolve.

Another oee of this bar is to prevent the rear portion of the harrow from being folded up, when the bar is turned upon its side, and thus to insure .the ei'ective working of the Whole surface of th'e barrow, by preventing the rear portion from gliding over the surface of the ground without its teethentering therein to the proper depth.

This machine is intended for sowing, drilling,dor planting, and when applied to one or the other purpose, the machine is properly adjusted by changing the parts.

Thus, when used for drilling, the parts G', L, L', and L, are detached, the machine then consisting ot' the parts D, E, (l, (arranged as described, in one chamber,) G, I.

When used for sowing grain, the parts E, G, L, Ll, l

and L, are used, the parts G and I beingA detached.

In planting ern,`the parts G and K are used, the parts E, I, and L, L, and L2, being detached.

The feed-bar D is to be used for all the purposes of drilling, sowing, and planting, and the hopper C altered as mentioned, so as to be subdividedwhen used in planting corn.

Instead of the hanow, I also propose to use shovel` plows, attached so as to be raised in the same manner as the hai-row, to be used to cover the grain when sowed.

lVhat I claim as my invention, and vdesire to secure by Letters Patent, is-

1. The combination of the hopper C and lever C', with the cams and the rods deriving motion therefrom, when so arrangedvthat the rodsmay be thrown out of gear by the action of the lever, substantially as set forth.

2. The combination ofthe feed-bar D, sieve E, and.v

trough F, and tubes F, `'suhstatntially as set forth.

3. The' combinationof the cutters Ltubes F, and revolving harrow L, 'substantially as set forth.

4. The combination of the donblerevolving barrow
